Suddenly, like lightening, the corn market drops to limit down. "Limit down" is the maximum the corn market can drop in one day. For corn it is 30 cents or ($1500.00 (each penny equals $50.00.) December corn traded at $3.6725 per bushel down the limit.

Why did this happen? Berry and Rees reported that today the Agriculture Department released its report on corn plantings which forecast 87.035 million acres up from 85.982 million acres planted in 2008. More acres mean more corn and more corn means lower prices.

Are financial stocks a buy now? Jeffrey Palma, a strategist for UBS says yes. He is recommending a modest "overweight" for this sector. He goes on to say that financials had the biggest gains among 10 industry groups in the MSCI World Index in the second quarter.

Let's be clear here. Mr. Palma is referring to the second quarter. The second quarter is done, finished. The real question is whether or not, going forward, the rally will continue.

POT's full second-quarter results will be reported on July 23. Analysts surveyed by Thomson Reuters are looking for a profit of 81 cents per share, on average.

E*Trade Financial Corp. (NASDAQ: ETFC) has garnered three upgrades in as many days this week. On Monday, Fox-Pitt upped the equity from Underperform to In Line, while FBR on Tuesday raised its opinion from Underperform to Outperform. Raymond James rounded out the trifecta on Wednesday, hiking its rating on ETFC from Underperform to Market Perform.

Judging by this rush of analyst love, Wall Street seems to think the worst is over for E*Trade. However, most of this week's commentary falls under the category of "damning with faint praise." For example, Fox-Pitt said they now believe ETFC is more likely to be acquired by another firm than to file bankruptcy, and Raymond James observed that the stock has "limited downside" -- hardly a bold statement for an equity that settled Wednesday at $1.23.

Listen to what Richard Parkus of Deutsche Bank has to say about commercial real estate. He said that "We are not only not approaching stability, we are at a period of maximum deterioration."

We have often said that after the collapse of residential real estate in the last year, the next shoe to drop would be the commercial market. What is being wrung out of the home market is now beginning to be felt big time in commercial real estate. Landlords are putting together all kinds of packages, including free rent and other perks, and still prices are falling. It is believed that values are down a whopping 50% from their peak in 2007.
